Is there an easy way to compare two association rules? I would like to find out if same/similar rules are found in two market-basket sets that contain the same features/class. Ideally I want to compare the left sides of the rules. I thought I could do this by reverting to data instance comparison but that is not clear how to do either. Is there a functionality to support set operations for datasets (data instances, association rules, etc) in Orange?

Data instances are hashable/comparable but only on the regular features/classed and not meta attributes.Unfortunately for rules induced by AssociationRulesSparseInducer on sparse basket datasets the 'left' and 'right' attributes will have only meta attributes/values. This means you would have to implement the comparison yourself.
